One of the more interesting technologies I discovered during my recent trip to Tech Ed 2014 is SignalR, which is a library for ASP.NET that allows real-time communication between the server and browser. This exciting platform enables bi-directional communication between a page and the server, allowing updates to be instantly pushed in either direction. Best of all, SignalR automatically detects the best option for communication based on the capabilities of the client ensuring maximum compatibility across different browsers.
To learn more about SignalR and see it in action, I highly recommend you check out this session from Tech Ed: Building Real-Time Applications with ASP.NET SignalR.
Today we’ll see how you can setup Sitefinity to use this library with a simple notification that fires when a user logs into the backend. Later we’ll build a more real-world scenario by building a real-time viewer count for a blog post.

Microsoft’s App Studio is a fantastic tool to help you design and generate applications for Windows Phone as well as Universal Apps for both the phone and Windows. The online interface allows you to add content like RSS feeds, Facebook pages, Flicker photos and more with a few clicks, generating a complete Visual Studio solution that can immediately be launched on the phone or desktop.
Today we’ll look at how we can enhance the App Studio solution’s Portable Class Library so that we can use Xamarin to add an Android version of the app.

InitializeComponent does not exist in the current context
